Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a servo system and a resonance suppression method thereof, the servo system comprises a wave trap group, the wave trap group comprises a plurality of self-adaptive wave traps,and the resonance suppression method of the servo system comprises the following steps: obtaining the resonance frequency of the servo system; when it is determined that the servo system meets the resonance suppression condition according to the resonance frequency, determining a corresponding resonance parameter according to the resonance frequency; selecting a self-adaptive wave trap from the wave trap group to update a resonance parameter of the resonance frequency so as to carry out resonance suppression on the servo system, wherein the updated resonance parameters are stored by the self-adaptive wave trap in the wave trap group. According to the invention, self-adaptive wave trapping can be carried out on a plurality of resonance points, and resonance suppression can be carried out ondifferent resonance points.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a servo system and a resonance suppression method thereof. Background technique [0002] In the motor servo system, the motor is usually connected to the load by a transmission mechanism such as a transmission shaft, a gear or a coupling. The mechanical transmission part of the servo system often uses transmission devices such as transmission shafts, reducers, and couplings to connect the motor and the load, but the actual transmission device is not an ideal rigid body. During the torque transmission process, the transmission device will show a certain amount of elastic deformation. , which will cause mechanical resonance of the motor torque, motor speed and mechanical transmission torque, and the system will emit noise. When the servo system works in the state of mechanical resonance for a long time, the transmission device will also be seriously damaged, causing industrial accid...
